Two contrasting theories-actor-network theory and nondecision making-are separately applied to the same case study, namely, technologies for automatically identifying road vehicles. By this process, the strengths and weaknesses of each approach are highlighted: The actor-network approach is useful for understanding local processes but lacks tools for easily illuminating patterns across countries; by contrast, the concept of nondecision making is useful for explaining the general lack of implementation of technology for automatic vehicle identification but not for explaining variations between developments in (...) different countries. This study highlights the importance of attempting to compare theories by using the same case study. (shrink)

Despite growing interest in evolutionary economics since the 1980s, a unified theoretical approach has so far been lacking. Methodological and ontological discussions within evolutionary economics have attempted to understand and help rectify this failure, but have revealed in turn further differences of perspective. One aim of this article is to show how different approaches relate to different levels of abstraction. A second purpose is to show that generalized Darwinism is some way from the most abstract level, and illustrates how it (...) may be used to move towards more specific theoretical applications. Nevertheless, there is a long way to go before these become more evident. (shrink)

Representation was invented as an issue during the 17th century in response to specific developments in the technology of simulation. It remains an issue of central importance today in the design of information systems and approaches to artificial intelligence. Our cultural legacy of thought about representation is enormous but as inhibiting as it is productive. The challenge to designers of representative technology is to reshape this legacy by enlarging the politics rather than the technics of simulation.
